yes it seems most likely that was the problem all the time that the teeth was worn funny no one now I had all my surgery and had this other guy notice. My dealership says I can't buy that part separately that I need to buy a new starter $1,200 . Unless I can find a used one and use that part. Hope some one here has a old one laying around that the teeth gear think is good. My mechanic says he might be able to file it to make it work better. But would rather see if I can locate that part.
